eciaimsl, (c1. 210 57) This invention relates to the purification and acceleration of lubricating oilsin internal'combustion motors of. the type conventionally employedin the operation of motor vehicles and aircraft,.,as well as stationary motors, and it has particular reference to a centrifugal device adapted to be installed in alubricating system by; connecting the same into the lubricant flow line, and its principal object resides in the provision of an assembly of parts including a reservoir-for-the collection of the heavy, undesirable constituents of the lubricant, such as abrasives, motor cut= tings, heavy particles of carbon; and the like,

whichimpair the lubricant as such and greatly-- decrease its efliciency.

Another object of the invention resides in-the provision of a device of the characterdescribed which aids in the acceleration of the flow of the lubricant through the system (1110130 the elimination of the contaminating constituents heretofore mentionedand boosting the flow in a manner'similar to the action of a fuel pump.

An object of the invention is also manifest-in the provision of an arrangement wherebythe lubricant may be subjected to a cooling action,

being brought in close contact with the atmos phere and subjected to air cooling arrangement of the motor with which it is employed, thereby greatly minimizing the normalrunning tempera ture of the oil and greatly increasing theefficiencyof the motor.

Broadly, the invention seeks to'comprehend the provision of apparatus embodyinga mechanical arrangement whereby theimpurities in the lubricating oil of an internal combustion engine may be separatedout by centrifugal action ap-- pliedthrough the movement of the oil itself flowing through the system and wherebysuch impurities, including water, and other foreignsubstances, as can be precipitated to the bottom of a reservoir ora container and subsequently drawn ing a'portion of the coverplatecut away"and illustrating the rotor;

Accordingly, therefore, the invention comprises a preferablycylindrical reservoir or container lhaving'an outwardlyextending 'flange Taround its upper rim, as illustrated in Figure 1. The bottom of the reservoir I is slightly concave in-ordera to properly drain fluid therefrom through" a drain valve 3threaded' into a boss lintegral'with the bottom of the reservoir I A pan or cup 5, provided with an-outwardly' extending fiange-around its upper rim, and of somewhat'lesser diameter than the interior circumferenceof the reservoir I, is inserted into the top of the latter andallowed: to depend thereinto, the flange 6 being'supported by the'circulari flange 2 of the reservoir I.

the member 5 and the interior of the reservoir 1.

The apertures 1 are arrangedfinthewalls ofjthe The memberw5 ispan .5 at thebottom thereof. illustrated in perspective in Figure 4.

Arranged for'rotation within the member 5a rot-or 8 is provided whichis pivotedfcentrally in:

the bottom of the member 5, as-illustratediin Figure 1, by a pin 9 adapted .to bethreaded-into a boss) depending below the bottom of the pan 5. The rotor-8 has an integral hub H projecting upwardly centrally of the member-8 afiording. a suitable: bearing therefor. formed with a plurality of radially arranged vanes 12 which have been previously cut from the outer rim of the member '8 and turned upwardly at right angles with respect thereto, as illustrated particularly-in Figure 4.

The rotor 8, being pivoted at 9 in the bottom of.v the pan5, is free, to rotate, when impelled by a: stream of fluid, or the like, projected through a nozzle l3 having a relatively small jet in the discharge endthereof anclwhich is directed tangentially with respect-tothe inner wall. ofthe pan 5, as:.illustrated in Figures 1and2; The nozzle 1 3 is arranged, preferably in:one edge of a: covenplat'etl a adaptedfto besecured by sorews I 6- A series of apertures, l are arranged around the wall of the memberi, forming communications between the interior of The rotorx8' is" or other medium, to the annular flanges 2 around the upper rim of the reservoir I. The screws l6 are adapted to extend through the flange 6 of the member and therefore retain this element in position. It will be noted that, by reason of the fact that the member 5 is of lesser diameter than the internal diameter of the reservoir 1, this member assumes a concentric position with respect to the reservoir l and an annular space a is provided therearound. The apertures. 'l are adapted to communicate with the annular space a, as shown in Figure 1.

The boss l3, therefore, is provided with an integral hood ll which is interiorly threaded to receive an oil line It communicating with the crankcase of a motor l9, as schematically illustrated in Figure 5. The cover plate is provided with central bosses and 2|, as illustrated in Figure 1, the upper boss 29 being interiorly threaded and adapted to receive the outlet lubrieating line 22, illustrated in Figure 5, and which also communicates with the crankcase of the motor I9 and conveys the lubricant back through the said motor. The boss 2| projects downwardly from the underside of the cover plate !5 and is exteriorly threaded to receive a nut 23 retaining a downwardly and concentrically arranged baffle 24. The bafiie M is circular in formation and extends downwardly around the pivot 9 of the member 8. The member 24 has an integral annular baflie plate 25 secured to itslowermost rim.

The rotor 8 is also provided with a plurality of spirally arranged blades 25, illustrated in Figure 3, which extend downwardly from the pivot l I terminating in certain of the recessions 21 around the periphery of the rotary member 81 and which are formed by cutting out the vanes l2 which have heretofore been referred to. The spiral blades 26 are of such depth as to be disposed for operation beneath the horizontal plate 25, illustrated in Figures 1 and 2..

In operation, the lubricant through the medium of the conventional fuel pump is circulated from the crankcase of the motor l9 through the conduit l8 and the nozzle 55 and is projected against the vanes l2 of the rotor 8 causing the latter to rotate within the pan 5 which forms a separating chamber 28 within the upper portion of the reser-' voir I. The lubricant passing into the chamber 28 through the nozzle l3 in the orifice l4, upon entering the chamber 28, will receive a centrifugal separating action within the chamberzfi by the spirally arranged blades 25 previously described. The blades 26, by reason of their form and arrangement, direct the fluid outwardly against the wall of the member 5 and through the apertures l therein allowing the heavier constituents of the lubricant to be precipitated to the bottom of the reservoir l The circulation of the lubricant is completed by passing beneath the horizontal baffle 25 and up into the circular depending baffle 24 and out through the bosses 2G and 2! and the conduit 22 back into the crankcase of the motor IS. The action, therefore; to which the influent is subjected separates out the heavier particles of sand, grit, motor cuttings. and the like, as well as water and undesirable fluids becoming commingled with the lubricant in the crankcase.

At desirable intervals fresh oil may be introduced into the assembly through a pillar opening 29 normally closed by a plug 30 in the cover plate [5. The sludge and undesirable properties of the oil which are deposited in the bottom of the reservoir I may be drawn off through the drain cock 3, previously described.

Obviously, the bafiling arrangement 24 and 25 may be of a form in which the horizontal portion of this member is eliminated. It is desirable, however, to form the baflling assembly so that a sufficient b-aliling surface is presented to the liquid to insure the complete separation, in cooperation with the spiral blades 26, of the injurious constituents of the lubricant from the liquid and cause the same to be drawn out by centrifugal action through the apertures 1 and be permitted to precipitate into the reservoir I, as previously described.

Manifestly, the structure herein shown and described is capable of considerable changes and modifications from time to time by those skilled in the art and such changes and modifications as may be resorted to which may be considered as falling within the spirit and intent of the invention may also be considered as falling within the scope of the appended claims.
